The Purity Fist is a community-created promotional cosmetic item for the Heavy. It is a heavily-augmented biomechanical limb with a Sarif Industries Logo near the base of the arm that replaces the Heavy's left arm.
The Purity Fist was awarded in Genuine quality to players who pre-purchased Deus Ex: Human Revolution on Steam before August 26, 2011, and to attendees of the Square Enix booth at PAX Prime 2011 and the 2011 New York Comic Con.
- The Purity Fist was added to the game.
- [Undocumented] Updated the item type to "Cosmetic Augmentation".
- If a Spy disguises as a Heavy with this item, the Spy will only have the arm robotic, but not the hand of the Heavy.
- The Purity Fist is a word play on "Purity First", a radical anti-augmentation group in Deus Ex: Human Revolution.
- The texture of the fingers is the same texture used on Heavy's ammo belt.
